2. The teeth of some reptiles that have no roots and are joined to the jawbone.

aerodontalgia

1. Toothache experienced at lowered atmospheric pressures, as in aircraft flight or in a decompression chamber, caused by the expansion of air in the maxillary sinuses.
2. Dental pain caused by either increased or reduced atmospheric pressure; also aero-odontalgia.

aerodontics, aerodontia

1. That branch of dentistry which is concerned with effects on the teeth of those who are flying at high altitudes; either at increased or reduced atmospheric pressure .
2. A branch of dentistry concerned with the prevention and treatment of aerodontalgia.

A congenital absence of the teeth other than by extraction or impaction: The dentist built a set of dentures for Muriel to make up for the anodontia in her upper jaw when she was born.

Anodontosaurus

This nomenclature, meaning toothless lizard is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Euoplocephalus aucutosquameus. Named by Charles Hazelus Sternberg (1850-1943) in 1929.

Relating to the atlas and the dens of the axis.

The dens is a strong toothlike process projecting upward from the body of the axis, or epistropheus (pivot), around which the atlas rotates.

barodontalgia

Toothache associated with the reduction in atmospheric pressure in high-altitude flying. Also: aerodontalgia.

1. A reference to the shortness of one or more teeth: "The dentist noticed that his patient had several brachydont teeth which needed crowns to provide better chewing when eating."
2. Relating to mammals with a primitive type of grinding tooth that is characterized by a low crown.
